GABION FOR PROTECTING RIVER-BANKS.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed August 20, 1906. Serial No. 331,394.

To all whom it may concern.-

Be it known that I, GAETANO Mnem- FERRI, a subject of the King of Italy,and a resident of Zola Predosa, in the Province of Bologna, Kingdom ofItaly, have invented certain new and useful Improvements in Gabions for.Protecting River-Banks, of which the following is a specification.

This invention relates to gabions for protecting the river-banks, itsobject being to provide box-like gabions made of a metallic latticewoven in a suitable form and bent afterward in such a way as to make abox with plain faces that will be filled with stones like the ordinarygabions.

In the accompanying drawings, Figure 1 shows the iron-wire latticebefore bending, and Fig. 2 the gabion completed after the lattice hasbeen suitably bent. Figs. 3, 4., 5, 6, and 7 show examples of othersuitable forms of lattices for fitting gabions.

The same reference-letters a l) c d e f throughout the figures indicate,respectively, the portions of metallic lattice that are designed to formbottom a, sides I) 0, ends at e, and cover f of the box.

The lattice instead of being in one piece may be in several pieces,corresponding toparts a b 0 cl 6 f, tied together with iron wire. Thegabion is made as follows: The lattice is bent along the common sides ofportions (1 b c d e f and the near edges are tied together byinterlacing iron wires.

Fig. 1 shows a form of lattice in which cover f is next to side 0 andends (1 e are next to bottom a.

In Fig. 3 the parts (2 f e are next one to the other in one piece nextto bottom a.

In Figs. 4 and 5 cover f is in two parts f and f of equal, Fig. 5, ordifferent, Fig. 4, size next to elther end (1 e.

In Fig. 6 ends (1 e are next to side I). Ends (1 a could be in the sameway next to cover In Fig. 7 cover f is narrower than bottom a and ends(I e have the form of a trapezium whose bases are equal, respectively,to the widths of bottom a and of cover f. In this way is made a gabionWhose cross-section is a trapezium, which gabion is specially fitted tocurbed revetment.

By opening suitably the angle between sides b and c the gabion may befitted to revetment of any cylindrical surface Without leavinginterstices between two adjoining gabions. If also bottom a has atrapezoidal form, the gabion may be fitted to conical revetment, asrequired sometimes.

Having now particularly described my invention, I declare that what Iclaim is- 1. Box-like gabions for protecting river banks made by bendingand tying in the form of a box with plain faces one piece or more piecestied together, of iron-wire lattice of suitable shape.

2. Box-like gabions having according to the shape of the iron-wirelattice, from which they are made, trapezoidal section, in one or twodirections as substantially set forth, and for the purpose specified.
